When does remediation do more harm than good? After conducting a sustainability analysis on a large pump‐and‐treat site at the Massachusetts Military Reservation (MMR), the Air Force Center for Engineering and the Environment (AFCEE) found evidence suggesting that the remediation systems were creating more pollution than they were remediating. For several years, the AFCEE/MMR has had an aggressive “better, cheaper, faster” optimization program intended to expedite aquifer restoration, reduce costs to the taxpayers, and reduce cleanup time frames. An initial sustainability analysis was conducted in 2005 as part of this program. The analysis identified several concerns, one of which was the indirect generation of air emissions from conventional fossil fuel–based power plants used to power the remediation systems. In addition to the environmental impact of these air emissions, the cost of electricity continues to increase. The AFCEE/MMR evaluated options for addressing both of these concerns and opted to employ renewable energy technology in the form of a utility‐scale wind turbine. This case study presents a more sustainable approach to remediation at the MMR through the use of renewable energy, in the form of a 1,500‐kW wind turbine. Power costs for operating the treatment systems, which processed up to 16 million gallons per day, amounted to over $2.2 million in 2008. The wind turbine is anticipated to reduce the program's electricity costs and offset air emissions, generated indirectly through the use of electricity from fossil fuel–based power plants, by approximately 25 to 30 percent. Based on a range of utility cost projections and an estimate of the turbine's energy production, the $4.6 million project is anticipated to have a payback period between six and eight years. © 2010 Wiley Periodicals, Inc. * This article is a U.S. Government work and, as such, is in the public domain of the United States of America.
